I get this error when I try to start the game:

[1]    20859 illegal hardware instruction (core dumped)  ./idu15.2/main

OS: Arch Linux

WM: X11

GPU: NVIDIA GeForce GT 440, driver: nouveau

Hi,

Unfortunately, it seems that your computer can't run it.

This specific error looks like missing support for AVX2 in your CPU, but the game also requires Vulkan support and I think GT440 doesn't have it.
